A new simulation model for inhomogeneous Au/n-GaN structure
(Pleiades Publishing Inc, 2016)
The larger the device area, the more difficult to carry on homogeneity during the fabrication and following treatments. Structural inhomogeneity may indicate themselves in variations in local electronic device parameters. ...
Exact analytical solution of the diode ideality factor of a pn junction device using Lambert W-function model
(2007)
The paper presents a new analytical method for extracting the diode ideality factor of a p-n junction device using Lambert W-function model and the dark current-voltage data. The extracted values are found to be in good ...
Magnetic and Magnetocaloric Properties of High-Energy Ball-Milled Nanocrystalline CeMn2Ge2 Compound
(Springer, 2016)
CeMn2Ge2 nanopowders have been obtained by high-energy ball milling for 5 and 10 hours from bulk compound to investigate the effect of milling time on magnetic and magnetocaloric properties. CeMn2Ge2 nanopowders have been ...
Peculiarities of thermo-morphologic and thermotropic transformations of heterophase regions: nematic <-> isotropic phase transition in 4-n-Alkyl-4 '-cyanobiphenyl mesogens
(Natl Inst Optoelectronics, 2019)
Important peculiarity of phase transitions in liquid crystalline materials is availability of the heterophase regions, in which low temperature and high temperature phases simultaneously take place. In this work, peculiarities ...
Regimes of current transport mechanisms in CdS/CdTe solar cells
(Iop Publishing Ltd, 2019)
Forward bias recombination (current transport) mechanisms have been evaluated for thin film solar cells and correlated to the in-gap trap levels present. Here CdTe/CdS devices were chosen as an archetypal example of a ...
High-diffraction-efficiency Fresnel lens based on annealed blue-phase liquid crystal-polymer composite
(Taylor & Francis Ltd, 2019)
We demonstrated a relatively simple and effective method to fabricate a periodically isolated polymer wall of blue-phase liquid crystal Fresnel lens (BPLCFL) by employing a single-masking process of the ultraviolet (UV) ...
The effects of preparation temperature on the main electrical parameters of Al/TiO2/p-Si (MIS) structures by using sol-gel method
(Springer, 2009)
In this study, the forward bias current-voltage (I-V) and capacitance-voltage (C-V) characteristics of the Al/TiO2/p-Si (MIS) structures derived using the sol-gel method have been investigated and compared at various ...
Effect of a Trifluorophenyl-Based Monomer on the Electro-optic Performances of Polymer-Stabilized Blue Phase Liquid Crystals
(Springer, 2020)
We synthesized one novel mono-functional acrylate monomer. The effect of the new monomer on blue phase liquid crystal stabilization and electro-optical properties was investigated with different reactive polymer concentration ...
Production and characterization of liquid crystal/polyacrylonitrile nano-fibers by electrospinning method
(Springer Link, 2021)
We present that high birefringent nematic liquid crystal, 4-n-pentyl-4'-cyanobiphenyl, was incorporated into the polyacrylonitrile precursor which has a strong polar cyano group so as to produce electrospun nano-fibers, ...
Quantum Hall effect in a high-mobility two-dimensional electron gas on the surface of a cylinder
(Amer Physical Soc, 2009)
The quantum Hall effect is investigated in a high-mobility two-dimensional electron gas on the surface of a cylinder. This special topology leads to a spatially varying filling factor along the current path. The resulting ...
